MOSGROVE, PENNSYLVANIA.

PatentedNov. 28, 1905.

To all whom, it'mag/ concern:

Be it known that I, BRUCE CLARK WHITE, a

United States'residing at Mosgrove, in the county of Armstrong and State of Pennsylvania, have invented or discovered newand useful Improvements in Glass-Rollingl Machines, of which the following is a Myfinvention has relation to machines for rolling a plurality of glass sheets separately and uniting them into a single sheet with or withoutan included wire-netting or other open metal network.

My invention has also relation to certain details of Construction.

It is the object of my invention to produce a single 'sheet of glassby forming separate sheets of glass between separate pairs of rolls andlthen unitngthesheets by means of another pairof rolls and, if desired, simultaneously including a woven or twisted wire netting or its elquivalent open metal network in the finished s ieet. v l

My invention has in view other objects whereby the glass may be conveyed from the forming-rolls at the desired speed and trans'- ferred to ai'leer or leers.

Other objects will appear in the description to follow.` f-

Referring to the drawings, Figure 1 is a side elevation ofmy invention, thelower portion of the eonveyerbeing broken off; Fig. 2, a plan thereof; Fig. 3, an; elevation of the side of my machine opposite that shown by Fig. 1, parts being in section; Fig 4, across-section on the line 4 4 of Fig. 3;' Fig. 5, a left-hand end view of the upper partiof Fig; 1; Fig. 6, a sectional detail showing the means for locking together shafts-29an'd' 7 and Fig. 7. a fragmentary sectional' detail showing the movable rguide for the glass beneath one of the lower rolls.

' @nthedrawings'l show three pairs of rolls y 1 2 Ian`d}3 4 and 5 6, the pairs 1 2 and 3 4 being ,preferably in thesame plane and the .pair

G arranged in such relation to the other two pairs that the Space or `pass between the pair 5 6 isfhetween theplanes of delivery of the pairs 1 2vand 3 4.` he necks of the rolls 1 to 4 are provided with'gear-'whcels 7, meshing .with the worms 8 on the shaft 9, which has thereon the' fixed and loose pulleys 10 and 11, driven by the belt 12.

13 is a shifter for the belt l2.

The shaft 9 carries a'spur-gear .14, meshing with the idler l5, which in turn meshes with l the spur-"ear 16 on the shaft 17. The latter boxes of the rolls 2 and 3 are stationary, While Athe rolls 1 and 4 are adfrom their companion rolls by means of the screws 23, journaled in the blocks 24 betweenv the ends of the bars 20, the screws working in the bosses 25 on the blocks. The outer ends of the screws carry sprocket-wheels 26, connected by the chains 27 to the sprocket-wheels 28 on the shaft 29, vwhich is operated by the hand-wheel 30, as shown on Fig. 5.

the journal-blocks of just-able toward and rolls/5 and 6 are supported between the bars 31, secured to the lower ends of the castings 21, the roll 5 being shown adjustable toward and from the roll 6 by means of the screwshafts 32, working in the bosses 33 on the journal-blocks. with sprocket-wheels 34, geared by the chain 35 to the sprocket-wheel 36, which is secured l to the tubular shaft 37, sleeved on the shaft 29. The shaft 37 has one end slit longitudinally and. threaded, and on the threads runs 1 the nut 38, by which the slit end of the shaft may be contracted, so as to frictionally unite vthe shafts 29 and 37. The sprocket-wheel 36 is preferably twice the diameter of the wheel 28.

Supported bythe upper bars 20 are two hop- I pers 39 and 40, the former' located above the I rolls l and 2, so as to feed molten or plastic glass down between said rolls, and the latter arranged to feed glass down between the rolls 3 and 4. i The castings 21 support the brackets 41, having slots in which the two guides 42 are secured and adjusted'. These guides lead one from the pass of the rolls v1 and 2 to the'pass of the rolls 5 and 6 and the other from the pass of the rolls `3 and 4 to the pass of the said H tolls 5 and 6. f Leading from the pass of the rolls 5mandv6 f is the roller-feed table 43. It has the parallel l side plates 44, to the under side of which are journaled the lower set of "ollers 45, all lying and lower parallel pairs of bars 20 'Y The journal blocks or boxes of the lower' The shafts 32 are provided85 IOO Y 5 and the upper roller 45 is the gui( 4ers of the table ers 45 and bon has ya very low conductivity 'for heat as 'f the glass which hardening so rapidly.' its coeiiicient ci ex-` `temperatures used,

The latter is driven by the bevel gear-wheel i 49 thereon, which meshes with the gear-wheel 5() on the drive-shaft 5l., carry and loose pulleys 52 and 53, actuated by the belt 54. The shifter serves to move the belt from one to the other ol said pulleys. Each of the rollers 45, save the upper one, which cooperates with the roll 6, has above it a companion roller 56, journaled in a swinging frame 57, pivoted on the bolts 58. The rollers are preferably driven by the gear- 'wheels 59, connecting the pairs of rollers. ri`he rollers 56 are connterweighted by adjustable weights on the arms 6() olf the frames 57.

Between each successive two olIv the rollers 45 is a guide 6i to support and guide thc glass from one roll to another, and between the ro le The secured to the bar 63, having'- the 64 secured to the bottom bars 3i. The bar 63 .is secured by the links 65 to the levers 66, having their upper ends in the path of possible outward travel of journal-blocks of the roll 5. li ribbed or other ligured glass is to be made, the lower of the rolls 45 will becorrespondingly ribbed or ligured, as will be readily understood.

At the outer end oi' the table 43 is a preferably tilting` table 6T; operated hy the handle i 68 or otherwise. When in one position, this table is in l'ne with the pass betweeil c rell- 4?, but when shilted it is in l line with the table or ledge 69, leading to the l leer 70 or other place oi' deposit, from which table the glass may be shoved horizontally into the leer.

Preferably l cover all the hoppers, the guides 42, 61, and 62, the rolls 1 to 6, the roll- 56, and the table 6i" with carbon, of blc-.cir on these sevehine. l find that carguide 62 is slotted ears indicated by layers eral elements of my i compared with iron and steel, and so'prevents 1s 1n contact therewith from pension is so small as to be negligible with Athe which prevents it from `served in thickness. r1[he friction'of glass with i carbon is very decidedly less than with metal,

The glass in the hopbetween the two pairs of forming the fixed i ing-rolls, formingr the two sheets 7 3, which l slide along' the guides 42 toward and into the pass of the rolls 5 and 6, where the two sheets unite into the ric "il along with them tween the rollers 45 and l56, which deliver the sheet oi' wire-glass upon ble 67. glass leaves them; lowed to rotate. delivered lroin shifted so as to sheet 7 4 and take the wire fabthrough the pass b ethe inclined ta- 'lhe rolls will be stopped when the but the rollers may be al- As soon as the glass has been the table 43 the table 67 is be in line with the table 69, when the sheet .is put into desired place. faster than theleer could apnea-l it, the table 67 could be made slidable transversely, so as to deliver to other leers. The foregoing etalls of operation refer to glass sheets of detinite or short lengths; but the apparatus is capable ci' use withwire `fabrics oflany the table delivering to the leer or elsewhere without the employment ofthe pivoted table 67. ylhe weights on the arms 60'wi adjusted to give the pressure required on the glass, and lthe speeds of thevrollers can be varied to suit the conditions, isthey are driven indeijiendently of the rolls. The rollersxserve to support, feed, smooth, and iiatten the 'sheets and deliver them to ythe table 67 Other sheets are made as above described, the operation being carried on indeiinitely. The rolls il and Qand' and 4 can .be adjustedl as desired by the rotation of the wheel() andthe roll adjusted in the same manner if the nut 38 has been rotated yto unite the shafts29 and 37. By making one set of rolls adjustable the thickness ci' the glassdelivered from the upper to the lower rolls-can be varied relatively to the size ci the pass between the lower rolls. W hen the ratio of the passes between the upper and lower rolls has been obtained, dif'- ferent thicknesses of glass may be made without disturbing the ratio by turning the wheel 36, iirst tightening the nut 38, because'the adjustment of the roll 5 is the sum of the adjustments of therol-ls 1 and 4. 1f for any reason it bev desired to pass the glassfrorn the rolls and 6 without allowing it to go own the table it can be done by pushing the `guide 62 against the roll 6, leaving a free open space for its escape below. It the hand-wheel The the leer or Iother If the glass should be delivered length,

in order to cool the' rolls,1l-

iownnd vprovide a' water creuetiontherein entering the ta.-

like-thesis! as follows: i make the necks of each roll hol low and close one neck by the plug 75 or otherwise. Through the opposite neck I introduce a pipe 7 6', which extends toward or to the opposite end of the roll. The pipe does not fit the neck closely, so that the water which iiows into the roll through the pipe 76 iiows out through the open neck of the roll into the trough 77, delivering into the. waste-pipe 78.

The cooling of the rolls prevents the metal shell from expanding and cracking the carbon cylinder secured upon it.

In continuous rolling of metal where a se ries of two or more rolls operate in succession, each producing a reduction, it is necessary that each succeeding pair of reducing surfaces should have a speed higher than that of the preceding surfaces proportional to the reduction effected by the succeeding pair; otherwise the metal between the two pairs of surfaces will be thickened up or will be caused to bend and form a loop. To prevent such thickening or distortion of the glass as it passes between the sheet-forming roll to the pressingrolls, provision is made for driving the pressing or lower rolls at a higher speed than the forming-rolls proportional to the reduction in thickness produced by the pressing-rolls, so that there may not be any distortion ot the sheets. It' a stretching act-ion is required, the speed of the pressing-rolls may be increased beyond that required to compensate the rcduction eii'ected by them. The speed of the pressing rolls can be varied by removing wheels la and 15 and substituting` wheels of different size. This compensation for reduction is efi'ected bythe compressing-rolls where two pairs of rolls are empiyed forming two sheets and one of said pairs is also employed for pressing the two sheets together. This will be readily understood when it is considered that the portions of the pair of rolls which compress the sheets have the same peripheral speed as the portions which form the sheets, and as reduction must occur during the pressing the pressing portions of the rolls will not take the sheets away as fast as they are fed thereto. Hence the space between the pressing and forming portions of the rolls will be filled. quickly. The lower rolls may be made longer than the upper rolls to receive the sheets as they widen under the action of said rolls.

In order to protect the metal network 7l from the heat and consequent oxidation, I may provide the shields oi' refractoryr material, as shown in Fig. 3.

If preferred, ribbed glass maybe made by making the highest roller 56 ribbed and removing the remaining upper rollers or providing them with a very soft material which would not injure the glass.
